Two different color in single bar in barchart

[#1]

Dear All,

My requirement is, i want to show two values in single bar chart with different colors like below.

I have two expression fields capacity &used and single dimension field container.

Say for example the container A ( My dimension ) of capacity 100% is filled with 30%.I want to differentiate the bar in two colors.

100 should be in one color and in that 30 should be in an another color ( like color in color in single bar ) Like below.

Thanks in advance

May be it would be easier to understand what you are trying to do if you can share a sample? Because as per your description, it seems like what I have proposed seem to work. I don't know how would it matter if we use one way or the other if the final output looks the same. But I may be missing something important
